vented new and useful Improvements in' Collapsible Heating-Stoves, ofwhich the following is a specification.

This invention relates to heating stoves, and more particularly to astove which can be readily collapsed or folded for shipping.

One of the main objects of the invention is to provide a stove of thecharacter stated of simple construction and light weight which may bereadily collapsed so as to cocupy a minimum of space for shipping, andwhich may be readily set up. A further ob ject is to provide a stovewhich is effectively locked a 'a-inst collapsing or folding when set up.Knother object is to provide a stove composed of a minimum number ofparts so constructed and related as to facilitate quick assembling ofthe stove. Further objects will appear from the detailed description.

In the drawings:

Figure 1 is a front view of the stove in set up condition.

Fig. 2 is a central vertical sectional view of the stove in set upcondition taken from front to back.

Fig. 3 is a section taken substantially on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail fragmentary section taken substantially online 4l4 of Fig. 1.

Fig. 5 is an enlarged fragmentary detail section taken substantially online-55 of Fig. 1.

Fig. 6 is a horizontal section taken substantially in the plane of line6--6 of Fig. 2.

Fig. 7 is a plan View of the stove in folded condition as assembled forshipment.

Fig. 8 is a sectiontaken through the stove in folded conditionsubstantially on line 88 of Fig. 7.

Fig. 9 is a fragmentary detail section of the meansfor securing the topon the stove. The body of the stove is formed of end plates 1 and 2 anda back plate 3 and upper and lowerfront plates 4: and 5, all of theseplates being formed of sheet metal of suitable gage. At their adjacentedges the plates are provided with interfitting inwardly pro jectingsleeves 6 which receive pintle wires edge of lower front plate 5.

7 which project below the plates and have their lower portions turnedoutwardly to provide spring elements 7*. lVire 7 passes through anopening in a web member 8 which extends across a foot member 9 ofsubstantially rectangular cross-section. This foot member is provided atits upper end with integral rectangularly disposed flanges or arms 10which fit snugly'about the corners of the stove when set up so as tolock plates 1, 2, 3 and 5 in extended relation and effectually preventcollapsing or folding of the body of the stove. When the foot member isapplied web member 8 is inserted over sprmg element 7 a the lower end ofwhich engages into the angle of the foot member, after which the footmember is pressed inwardly slightly toward the body of the stove so asto place spring element 7 under tension, the foot member being then slidupwardly into operative position, in which position it will beeffectively held by the action of spring element 7 which serves to pressthe flanges or arms 10 snugly about the lower corners of the body of thestove so as to secure the plates in extended condition as previouslystated.

A front opening 11 is left between the front plates 4 and 5, and a lowercorrugated forward edge with sleeves 13 which interengage with sleeves14 formed at the upper A pintle wire 15 is inserted through the sleeves13 and it so as to hingedly secure the reflector to plate 5. Thisreflector, when in operative position, fits snugly between end reflectorplates 16 which are secured at their ends about the pintle wires 7,these end reflector plates being positioned on the inner faces of theend plates 1 and 2 of the body of the stove.

An upper reflector plate 17 is hinged at itslower edge 2113.18 to theinner face of back plate 3 and is provided adjacent to its upper edgewith a stop strip 19 pivoted to the plate at QOand of .such length as tocontact with the upperjfront plate 1 when extended so as to support thereflector plate 17 at an inclination forwardly and upwardly of thestove. This leaves an opening 21 for escape of the products ofcombustion which flow into the space 22 in the upper end of the stove.Back plate 3 is provided with an escape opening 23 communicating withspace 22 and with a collar 24 surrounding this opening for attachment ofa pipe which may be connected to a flue in any suitable or preferredmanner.

Top 25 is formed of sheet metal of suitable gage and is provided with anarcuate de-" pending peripheral flange 26 adapted to fit snugly aboutthe end and front and back plates of the stove body. Each of the platesof the body is provided at its upper end with outwardly turned flange 27adapted to snap into flange 26 of top 25 when the top is forced over theupper ends of the plates. This serves to secure the top upon the stoveso as to prevent accidental displacement of the same, and the topservesto effectually lock the plates forming the body of the stove in extendedrelation and to effectively prevent collapsing or folding of'the stovebody. T he, top 25 is reinforced by corner plates 28 securedthereto bybolts, rivets, or in any other suitable or preferred manner. Thesecorner plates have depending arcuate flanges 29 which fit snugly aboutflange 26 of the top so as to efiectively reinforce the same and preventspreading apart of flange 26 when the top is applied. K

The end plates 1 and 2 are provided with openings 30 which are alinedtransversely of the stove when the stove is set up. These openings areadapted to receive a burner 31 of, a known type so as to support theburner above and adjacent to the upper portion of reflector plate 12.This burner is provided at one end with a depending nipple 32 adapted toreceivea hose for connecting the stove to a suitable source of supply ofgas,and with a control valve 33. A bracket 34; projects from nipple 32and fits snugly against the outer face of end plate 2. This bracketreceives a stove bolt 35 which passes through the end plate and isprovided on its inner end with a nut 36. This provides means for quicklyand easilv securing the burner 31 to the stove and insures that theburner will be properly positioned relative to upper reflector 17 Byremoving top 25 and foot members 9 and burner 31, the body of the stoveand the reflectors carried thereby may be readily collapsed so as tooccupy a minimum of space. To collapse or fold the body of thestove,,refiector 12 is turned upwardly to fit snugly against the innerface of upper front plate 4, covering the opening 11 as in Fig. 7, itbeing understood that reflector 12 has sufficient flexibility to bereadily moved into substantial parallelism with the front plate of thestove body. After this has been done, member 19 is turned so as to bepositioned within the outline of reflector 17, this reflector being thenturned upwardly so. as to fit snugly against the inner face of backplate 3. With the reflectors in the positions stated, thebody of thestove may be readily collapsed or folded in the manner illustrated inFig. 8, after which the top together with the burner and foot membersmay be placed upon the body, the whole stove when thus collapsedoccupying but very little space. As will be understood, the body of thestove and the top and burner and foot members may be placed in a cartonfor shipment in any preferred manner, the manner of packing illustratedin Fig. 7 being only one of many which can be employed. A stoveconstructed in the manner illustrated and described may be readilyproduced at small cost and can be quickly and easily set up or collapsedwhen desired. It is possible to ship twelve of these stoves in collapsedcondition in the space required to ship a stove of similar dimensions inset up or uncollapsed condition. This effects a material saving in thespace required for shipment which is frequently a very importantconsideration. As will be understood, it may be found desirable inpractice to resort to changes in details of construction and arrangementof parts of the invention, and I intend to include all such variations,as fall within the scope of the appended claims, in this application inwhich the preferred form onlv of my invention is disclosed.
